I finished this adventure a couple nights back. I liked it.

It takes old gamers way less than the 5/6 hours estimate to complete the adventure, but it's still definitely worth picking it up.

I'm not a fan of having red herring puzzles that don't seem to go anywhere, as well as stumbling upon solutions of puzzles before knowing you should be doing stuff, and there are a couple of those here, but they don't break the flow of the game much, because they are short paths. Also, I think I did not use all items I picked up: some I see are there as a sort of "quest log", or clue really, for the steps of other puzzles, and that makes sense in a way; I'm not sure about others.
